When a package is shipped internationally, it may be subject to import taxes, customs duties, and/or fees imposed by the destination country. We are unable to predict which of these fees, if any, will be applied, and the buyer will be responsible for these fees or taxes so please factor that into your purchase. Here are some general guidelines garnered from our research, but it is best to consult your nearest postal authority:
UK: If your goods (excluding shipping cost) exceed £15, you'll pay an additional 20% VAT on the entire cost of your order (including shipping), plus an £8 "handling fee" to Royal Mail. If your goods (excluding shipping cost) exceed £135, you'll also have to pay an additional 12% "customs duty" on the entire cost of your order (including shipping).
Canada: Flat $5 handling fee for USPS shipments.
Germany: Anything under €22 (price + shipping) is free of customs duties and import taxes, packages between €22-150 you’ll pay sales tax on price + shipping (19% as of August 2014), and over €150 you’ll pay sales tax and customs.
Brazil: Anything over $50 (including delivery) gets hit with a tariff and customs which can double the cost.
The Netherlands: A friend told us that anything over €22 (price & shipping) gets hit with sales tax (typically around 20% of the price including shipping). Anything over €150 will need to pay both sales taxes and customs.
Australia: Nothing to pay for import goods valued at up to AUD1,000 (~USD850). (Thanks Australia!)
Turkey: a friend told us there is a limit of €75 per shipment for customs. If the value of shipment exceeds that, you pay +20% of the total sum.
Sweden: 12% customs tax (of the total value of the order). 25% sales tax of the customs tax value.
Denmark: Any package from outside the European Union that costs less than 80 DKK for the items themselves will have no duties or taxes. Any package equal to or above 80 DKK, customs will add a fee of 128 DKK plus a sales tax of 25% on the entire amount.
Norway: Anything under NOK 350 (price + shipping) is free of customs duties and import taxes, if above that you pay 25% sales tax on the total sum. Customs tax depends on the kind of goods ordered, i.e. clothes are 10,7% which are added before the sales tax.
